Zac's passive should be reduced at later levels like Aatrox

Right now his passive has a cooldown of 300 seconds at all levels. I feel that's just too long late game. Zac isn't that weak though which is why I think this would be a good touch to his kit. As someone who dives in fights as often as and even more often than Aatrox the reduced cooldown on his passive would open up more risky initiations later on in the game. Plus if we're all honest Zac's passive is just a worse version of Aatrox's in most situations. And with that type of buff it'd sit him pretty, cause he's at a decent spot right now.
